Made in the USA, Vi Bella masks are sewn of two layers of closely woven fabric with a non-woven, filter layer sewn inside. The sewn-in filter layer is washable which means that you do not have to use any other one-use filters. Wash the entire mask after using and it will be ready to go the next day! Pleated design, elastic ear loops. Adult- one size fits most.
Adjustable masks (noted in description) have adjustable elastic ear bands and a wired nose piece to provide a perfect fit. Also made of two layers of closely woven fabric with a non-woven, filter layer sewn inside.
